[Brew] MAC Open JDK 설치.

오랜만에 mac 을 다시 설치하고, jdk 를 설치하려고 하니 기억이 안난다.

 

Oracle 에서 다운받아서 설치 하지 않고, OpenJDK 를 설치하기 위해서 brew 를 이용하려고 한다. 

 

1. brew 설치하기

mac 패키지 설치 툴은 brew 가 가장 유명한것 같다. https://brew.sh/ 에서 brew 를 설치해주자. 

 

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

 

한참 설치하고 나서 brew 를 업데이트 하자. 

 

2. brew update 하기

$ brew update
Already up-to-date.

 

3. Open JDK 설치하기. 

공식적으로 아직 brew 가 OpenJDK 를 직접 지원하지 않아서, 다음 사이트에서 지원하는 AdoptOpenJDK 를 이용한다. 

https://github.com/AdoptOpenJDK/homebrew-openjdk

OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.265-b01, mixed mode)

 

4. JDK 설치 경로 확인하기. 

% /usr/libexec/java_home -V

Matching Java Virtual Machines (1):
    1.8.0_265, x86_64:	"AdoptOpenJDK 8"	/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home
